AIMPROVEMENT IN ICE-MACHINES.

Specification forming part of Letters Patent No. l

68,500, dated October 5, 1875; application led July 1, 1875.

To all whom 'it may concern Be it known that I, AUGUSTE JAS, of New Orleans, Louisiana, have invented certain new and useful Improvements in Ice-Machines, of which the following is a specification:

My invention relates to that portion of icemaking apparatus by which the water is congealed and it may be considered an improvelnent upon the apparatus described in my Letters Patent No. 162JQ dated April 27, 1875.

My present apparatus, while retaining the characteristic features of my patented machine, is so modified as to be adapted to the freezing of large and thick blocks of ice.

The nature of my improvements will be understood by reference to the accompanying drawing.

Figure 3 is a vertical central section of the apparatus. It is composed of two boxes or chests, A B, which are, in thc present case, counterparts of one another, save that the npper one is of somewhat vsmaller dimensions than the lower one, to permit it to enter the water-vessel C, which rests on the lower one.

I shall now describe the structure of the chests. Each chest is made in two parts-D, Fig. l, and E, Fig. 2. Each part is composed of a single casting. The part D is a box-like structure, whose sides are on the inside of a height equal to the height of the ribs a on the other part E. The part E is a plate of suchdimensions as to lit accurately the open end of the box part D, with its border resting on the top or edges of the sides of the box. The two, when put together, are riveted or bolted, with a packing between them to make a tight The ribs a serve as partitions to form a serpentine passage through the chest. To this end, when the two parts D E are put together the longer edges of the ribs fit closely sides of the box, each rib at the opposite end stopping. short ofthe side of the box, in order to leave at that end a passage through which from one division to the next, as indicated by arrows in Fig. 2. The inlet is marked b and the outlet c.

ner in which the two parts of the apparatus are made. It will b e noted that I preserve the simplicity of structure and cheapness which as in said apparatus, each one of the present boxes or chests is made of two pieces, each of which may be a single casting, 'and which, when put together, will forni a receiver, thro ugh which the refrigerant is forced to travel in a serpentine path. The lower chest B, as above remarked, is of a sufficient area to receive the water-vessel which rests upon it, as shown in Fig. 3.

A more perfect contact may be insured by or moistened with an incongealable conducting liquid.

I would remark that, if desired, the lower chest may be provided with hollow sides to surround the sides of the water-vessel, and thus insure more perfect action of the refrigerant on the water to be frozen. These hollow sides may also be partitioned to cause the refrigerant to travel in a serpentine path.

The upper chest A is of size to t within the vessel O snugly, but without friction. It is designed to be suspended and sustained by any suitable mechanisms, by means of which it ma at any time be raised or lowerglglhptthe wil'lwoA Y, em,aitc-TM'I'lTfet'^'shown any such mechanlsm 1n the drawlng, lnasmuch as any of the ordinary means used for analogous purposes may be here employed.

The two chests, when in use, are coupled by flexible tubing d, or by equivalent means, such as metallic pipes with telescopic joints, through which the refrigerant, after it has traversed one chest, will be conducted to the other chest, which it will traversein like manner.

I then lower the upper chest until its under face is nearly, but not nl'ljtgdwimnMcontac.t..xuith the water. When t e Water is sufficiently frozen I introduce a new layer of water, which is in turn frozen, and I thus proceed unt-i1 I have built up a solid block of ice lof the requisite thickness. l

Having described my invention, what I claim,and desire to secure by Letters' Patent, is-

The described freezing apparatusconsist ing of two chests formedv each by the union of twopar'ts constructed and put together to constitute a hollow structure with internal serpentine passage, as described, the two chests being connected by iexible tubing, or its substantial equivalent, as specified, and adapted to operate in connection with a watermold or vessel placed between them, substantiallyas set forth. V

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

AUGUSTE JAS.
